  • PCPM-80

    From Thomas Stephens@21:1/5 to All on Thu Mar 21 16:10:32 2024
    I have been blessed (cursed) by the demon Murphy with some projects for
    CP/M.

    The first is the easier one, re-release the should have been released
    (lost, forgotten, missing release) CP/M 2.8 (P-CP/M 80). I have gotten a
    good start on this but have a few questions and problems.

    The DRI package is incomplete, it lacks part of the utilities and the CBIOS.

    I got from POLY.PLAY the last copy of new/old stock the manual and disk
    of Sharp MZ-800 PCP/M-80. I have a scaned and OCR'd PDF of the manual, I
    am working on making a clean ASCII text file of the manual. I have two
    versions of the disk, the original (MZ-2Z047v1.0a), and a slightly later version (MZ-2Z047v1.0b).

    1. Was PCP/M used on any computers other than the Sharp MZ-800?
    2. Does anyone have copy of the BIOS (source code preferred) other than MZ-800?
    3. Can you extract the files from two disk images for MZ-800? Have extended DSK images but have not found any thing that works on my
    windows tablet.
    4. Recomendations for a Z80 disassembler and debugger for Windows 10(32 bit). I need to disassemble the BIOS to source code for the CBIOS.


    Thanks

    I use an old MS-DOS version of IDA still that supports Z80.

    -uso.
